For some years, the height of ovens having horizontal chambers for the distillation of coal hasbeen inc'reasing m'ore' and" more, while the duration of carbonization, on the coontraryflends tobe reduced as much as possi le.

On the other'hand, owing to the fact-that the gas and chemical industries are utilizing more andmore'the gas produced by the distillationof coal in coke ovens, the quality which this gas must have necessitates that the car-bonization' chambers should beprovided withdoors which. are as'air-tight as possible, while being rapid in manipulation.

The result is that rudimentary doors luted with clay, which are not-very air-tight-,nor very easy to manipulate; and are costly and long, are inadmissible in a modern coking plant, andthe constructors of coke ovens have replaced them'bydoors of different constructions which obviate luting withclay.

'These doors consist essentially of anundetachable metal frame sealed in the mason ry oftheioven-, in which frame the door is hungby means which are more-or less complicated. Alr-tightness" between the frame and the door is effected either by means of a tact, and would not offer-any inconvenience if the door was always replaced exactly in 'more'orless elastic material (asbestos rope, metal rope), or without the. interposition of these yielding materials, air-tightness bemg then effected by'the perfect fitting ofthe con:

tact surface's -of-',the door andits frame.

Heretofo're, coke *oven doors, which "are not luted, am remained air-tight; for a rather short "time only, owing to the fact that, a

as regards those doors, the, tightness of'which is obtained by means of an elastic joint, the

saidjoint is hardenedrap'idly by tar, and as regards'those with finished metal joints, the tightness islikewise imperfect owing to the deposit .of layers of pitch on a portion ofthe finished surfaces. V :7 r r 1 These deposits oftar and pitch "canonly bejproduced-onthe portionsof the surfaces of the frame and door which are not in con- ;the same placein'its frame. =This c0ndition however, is not realized in'any' ofthe .sys-

; ,The present invention has for its object to oven without clay 1uting,'which is distinguished substantially from the known systems in the particularly simple means employedvin order to ensure that,when the door is operated, it will always place itself exactly and automatically in the same position in the frame serving for its seat, so as to avoid tar becoming interposed between the surfaces in contact of the door'and its frame,

Figure 18 is a plan corresponding to Figure 17. V

In the construction of the door shown in Figures '1 to 6, the hooks are fixed to the frame and the rollers tothe door.

In Figures 1 to 6, the door proper 1, provided with a suspension hook 2, co-operates with a rigid metal frame 3, built into the front walls 460 of the oven 4. According to r the invention, the frame 3 carries projecting hooks 5 along one side thereof and hooks 7 along the other side, co-operating with the rollers 6 and 8 respectively mounted on'crossmembers 9 in any suitable manner.

In the example shown in the drawings, the rollers 6, three in number, have a V-shaped groove 661', while the hooks 5 have a V-shaped section 5a correspondingto the V of the groove of the roller, the hooks and rollers constituting guides and the V-shaped section of the hooks and the V-shaped grooves of the rollers constitutingcomplementary projections and recesses. The said hooks 5 and rollers 6 are situated on the same side of the vertical axis of the-door, while the hooks 7 and rollers 8, situated on the other side of the said axis, are smooth so as to avoid the unequal expansion of the door and frame causing abnormal stresses on the fixing hooks 5 and 7. The cross-members 9 slide in the supports 10 integral with the door, the screws 11, placed in the middle of the cross-members, bearing against the door 1, and permitting the latter to be tightened on its frame 3.

The door being suspended by the hook 2 from a suitable wheeland axle, it is merely necessary to allow it to descend so that the rollers 6 engage in the hooks 5, which have their ilsurfaceinclined to the plane of the door frame for the purpose of facilitating the guiding of the door while it is descending and pressing the door to the door frame.

When the latter is brought into contact with theframe by tightening the screw 11 the rollers 6 are obliged to lit in the V-section of the hooks 5 and the door is therefore always appliedin the .same place of the frame.

The guiding of the door when it is placed in position on its frame may obviously be obtained in numerous other ways. Figures 7, 8, 9 and 10 show in this connection a modification in which use is madeof two V-rollers 6 fixed to the frame 3, while the hook 12 is fixed to the upper portion of the door and the wedge-shapedprojection 13 to the lower portion. It is easy to see by examining the drawings that this projection 13 is wedge shaped both transversely and longitudinally and that like the preceding device, obliges the door always to take up the same position on the frame. In this construction a roller 6 v is carried between the arms of a bifurcated bracket 66 extending from the bottom of the door frame; The roller 6 is carried by an axle 6?) having an eccentric central portion 60 upon which the roller 6 is mounted. The axle 6b is mounted in bearings 6d; l/Vith this construction, the position of the roller 6 may be adjusted by rotating the axle 6b in the bearings 6 The membersserving for the support of the door maybe constructed in quite a different manner from rollers with V-shaped grooves cooperating with hooks likewise having a V-shaped section. For example, the cross-members 9 of the door shown inFigures 1, 2, 3 and 4 maybe replaced by. the crossmembers 15 having'curved, tapered or wedge shaped ends 17 cooperating with lugs or right-angled irons 16, integral with the frame and constructed as shown in-Figuresll, 12, 13 and 14., which only differ from Figures 1, 2, 3 and 4 in the members serving to support the door.

Figures 15, 16, 17 and 18 show'the constructional details of the said supporting members as well as their co-operation.

It will readily be seen, on examining these figures, that when the door is lowered, the

.cooperation of the curved and tapered ends 17 of the bars 15, and of the channels 18, provided in the right-angled irons 16 will cause the door to be guided so that it must always be applied to the same place on the frame.

The invention is obviously notlimited by these constructional details and may vary according to the applications and according to the greater or lesser degree of perfection required. 1
